IMPROVEMENT IN WATR-WHEELS.

The S cheule xefen'ed to in theseLettei-s Patent and making part of thesame.

To all whom 'it 'may conce'r'n:

Be it known that I, FRANKLIN HoYT, of Montpelier, in the county ofVVashington, and State of Vermont, have invented certain new and usefulImprovements in Water-Wheels, of 'which the following is a full, clear,and exact description, reference being had to the accompanying drawings,which make part o'f this specification, and ilu which- Figure 1represents a Vertical section of my improved water-wheel at the line x xof fig. 2.

Figurc 3,.a view in perspective of the gates, 'and theimechanism bywhich they are moved, detached, an w Figure 4, a similar' view of thechutes, detached.

The object of my invention is to provide a waterwheel which shallpossess the combined advantages of a turbine and a breast-wheel, as wellas to afford an improved means of regulating and stopping'the supply ofwater thereto; to which ends,

My improvements consist,

First, in constructing the buckets of curved form, both vertically andlaterally, whereby the entering water acts upon them first by impact, asin ordinary breast, and aterward by gravity, as in turbine Wheels, ashereinafter described. w

Second, in a series of curved gates attached by pivoted arms to a ringwhich encircles them, and which sfirotated by gearing in such manner asto diminish on' close at pleasure the openings through which the wateris admitted to the chutes.

In the accompanying drawings, which showa' convenient airangement ofvparts for carrying out the objects of my invcntion, A represents thewheel which rotates in a casing or penstock, B, to which the water isconducted through the head-race B'.

A represents the wl'ieel-shaft, which bears on a step, al, on the frameA2. y

The buckets a of the wheel are curved radially ther'eto, as in turbines'of lordinary construction, andare, likewise, curved vertically for aportion of their length toward their lower ends,l which extend below thebottom plate b of the-casing B, and are surrounded, for this portion oftheir length, by a band, a, connecting their outer edges, and extendingnpward from the plane of their lower edges to the upper face of the'bottom plate b of the casing B, 'and formingarun'ningwater jointtherewith, as shown in fig. 1.

By this construction, the water is prevented from flying offcentrifugally from the buckets afteracting upon them by impact, and isretained until all that is let into the wheelshall have descended thewhole length of the bncket in the space between the band a and thehub-cylinder of thewheel, to be discharged at the bottom of the bucketswithout waste, after pro- The water is directed to the buckets by thecurved chutes f f which are united at top by a plate, F, through whichthe shaft Al passes, and secured at bottom to the casing B, the chutesbeing inclined toward the wheel, as shown in red lines in fig. 2, toproperly di- .rect the currents of waterthereto, i i

Curved gates, D, are placed within the chutes f, 'being secured -atone'end to pivots, d, mounted in hearings in the casing B, and connectedat their opposite cnds, by pivoted links, c', to a ring, O, which ing. I

Byirnparting rotary movement to the. ring O, by means of the pinion e,on the Vertical shaft E, gearing 'into teeth,.c, on the inner surface ofthe ring, the gates D can be moved so as to increase, diminish, or shutoff entirely the supply of water to the wheel, according as each gatc ismoved from or toward the to he regulated at pleasure.

Having thus fully described my inventi'ou,

Vi-fhat I claim, and desire to secure by Letters Patent, is-- p 1. Thewheel A, constrncted substantially as dea, and the band a, incombination 'with the bottom .plate b of the casingB, asand for thepnrpose speci fied.

2; The gates D I), in combination with the chutes f j; pivoted links'c'.;', and ring O, the whole arranged au'd Operating substantially, asand for the purpose described.

In testimony that- I ciaim the -foregoing a's my invention, I havehereunto set my hand and seal, this 6th day of March, '1869.
